Why do I feel like Brazil treated the match against Bolivia as a practice match? They were already certain to qualify beforehand, therefore Carlo Ancelotti experimented and rotated players in this match, but it turned out that the experiment did not bring victory for Brazil. This is clearly a good achievement for Bolivia because with this victory Bolivia still has hope of qualifying for the World Cup.
Without Messi, Argentina had to admit Ecuador's superiority. The match was played at a high tension, and I think one of the factors that made Argentina lose was the red card they received in the 31st minute.
Apart from the fact that Brazil had already qualified for the world cup and thus doesn't need to stress his players further with the match, it's still important to know that going to Bolivia and getting all 3 points is very difficult. You can host Bolivia and thrash them but not when they host you. It's difficult playing there for foreign players because they are not used to such high altitudes while playing which gives the Bolivian players this advantage over other teams.
